ICE-PICK.

SPECIFICATION forming part of Letters Patent No. 787,509, dated April18, 1905.

Application filed June 2, 1904. Serial No. 210,900.

To all whom it may concern.-

Be it known that I, CHARLES W. HALsEY, a citizen of the United States,residing at Evansville. county of Vanderburg, and State of Indiana, haveinvented certain new and useful Improvements in Ice-Picks, of which thefollowing is aspecification.

This invention relates to ice-picks.

My object is to provide an ice-pick which is simple, strong and durable,and -inexpen sive of manufacture,which will have improved provision forholding the points and permit removal of said points and replacement byothers, if desired.

In carrying out the invention I provide an ice-pick wherein the bodyportion is formed of duplicate stampings or castings of steel or othersuitable metal having portions forming sockets for the points and meansfor holding the points and for securing a handle to the body and hollowribs, the details of construction of which will appear more fullyhereinafter, while the novel features are recited in the appended claim.

In the accompanying drawings, Figure 1 is a view of the completeice-pick; Fig. 2, a view showing one of the halves of the body laid backto expose the interior and showing by dotted lines how the points lie inthe sockets; Fig. 3, an end View with the points removed; Fig. 4, anedge View; Fig. 5, a sectional detail view illustrating how the socketsmay be tapered to hold the points, and Figs. 6 and 7 detail viewsillustrating dififerent forms the points and sockets may assume.

Referring first to Figs. 1, 2, 3, and 4, the body of the device isformed of duplicate halves 1 and 2, which may be stamped or cast fromsteel or other suitable metal and formed with the half-round sockets 3,which extend inwardly from the straight edge 4 at the end of the body,the half-sockets on the respective parts 1 and 2 forming completecylindrical sockets open at their outer ends and closed at their innerends by the end wall 5. For purposes of strength without appreciableaddition of weight the halves 1 and 2 may be formed with hollow beads orribs 6 and 7,

which together form a tubular extension of the end sockets and curvebackwardly toward the handle portion 8 of the body, where a shoulder 9is formed and beyond which extends a hollow shank or tang 10, over whicha suitable handle 11 may be secured. The braces 6 and 7 give greatstrength to the device, and to provide abutments corresponding to thewalls 5 at the back of the end sockets 3 the shoulders or protuberances'12 are formed,which project toward each other across the end sockets inline-with the end walls 5 of the various sockets 3. The pick-points 13have round shanks, which are received in the sockets 3, and the diameterof these pickpoints is a trifle greater than the internal diameter ofthe sockets 3, so that said points will be firmly clamped to the body bythe use of the rivets or screws 14, which pass through the bodyintermediate the various sockets and also outside the end sockets. Thesefastenings 14 may either be rivets or screws, and I sometimes find itpreferable to use screws in order that the points may be readily removedat any time for replacement by others, and I do not wish to limit myselfto either the use of rivets or screws.

As illustrated in Fig. 5, the shanks of the picks may be made tapering,as shown at 15, and the sockets 3 are correspondingly tapered. Thegreatest width of diameter of the sockets is at the walls 5 anddiminishes toward the mouths of the sockets. This construction preventsthe picks from falling out; but with ordinary usage the plaincylindrical construction fills all requirements.

As shown in Figs. 6 and 7, the shanks of the picks may be made oval orrectangular; but these constructions are not as desirable as thoseheretofore set forth.

The shoulder 9 is not absolutely essential, and obviously a separatehandle 11 need not necessarily-be used, as the body of the device couldbe formed with an integral handle; if preferred.

The peculiar formation of the sockets and ribs permits the use of thesame thickness of metal throughout the'body, thus cheapening the costand lessening the weight of the tool, while also giving it greatstrength, and the formation of the body in duplicate parts does awaywith extra operations in process of manufacture.

As contradistinguished from ordinary icepicks the present ice-pick willchip ice into small particles.

Various changes of construction might be resorted to in carrying out theinvention, such as will suggest themselves to the artisan skilled inthis particular class of invention, and I do not limit myself to detailsof construction, except as stated in the claim.

Having thus described my invention, what 1 claim as new, and desire tosecure by Letters Patent, is-

An ice-pick having a body composed of duplicate parts having alternatingflat portions and substantially parallel matching half-sockets whosebacks constitute ridges on the exterior of the body and which extendinwardly from an edge of the body, and terminate in abutments for thepick-points, said body being also provided with converging matchinghollow half ribs or braces whose backs constitute ridges on the exteriorof the body and which join and continue as a single hollow handlecomposed of matching half-sections,

pick-points in the sockets aforesaid, and fastenings connecting the twoparts of the body together.

In testimony whereof I hereunto afiix my signature in presence of twowitnesses.
